Newcastle vs Arsenal: As it happened

Welcome to Standard Sport's live coverage of Arsenal's trip to Newcastle.

We'll bring you regular updates from St James' Park as Arsene Wenger's men look for their second away success of the campaign against Steve McClaren's side.

Laurent Koscielny has recovered from a mild back problem to start the Premier League fixture ahead of Calum Chambers, who struggled in the goalless draw against Liverpool on Monday.

Wenger believes the young defender's failure to make an appearance at this summer's England Under-21s European Championship campaign has contributed to a loss of confidence but backed Chambers to come back stronger.

The Gunners boss said: "I have spoken to him and he's a strong boy, a dedicated player who loves football, is ready to work day and night and he has the talent. He will be good player."

Meanwhile, Per Mertesacker remains sidelined for the visitors as he continues to battle a chest infection and Theo Walcott starts ahead of Olivier Giroud.
